New Corsair ML Fans

[Fassou]

The latest from Corsair is something to highlight, because it's not often that a company that usually presents quality products, brings out some fans with ML (Magnetic Levitation) technology, which make them much more expensive, reduce some noise, but do so by skipping including one of the main advantages of using this technology, taking advantage of the space occupied by the traditional central motors :facepalm:

In this mini article from Guru3D.com, which seems to be the product of some unpleasant contractual obligation, we can read the lamentable comments about the new fans from Corsair.

Salu2!

They remind me of the fantastic SilentX, a real marvel, which cost three times as much as normal ones, which after three months either jammed or started making a terrible scraping noise. Two things that SHOULD NOT happen according to their excellent performance. Now I have some tacens that are 4 years old AND they have not failed! They will make more noise (I don't think so) they will be of worse quality (I don't think so) and they are not colorful (black and white) but they don't fail. I'm scared of these.
Where there are some sunon or some papst let these be removed. They will surely make more noise, but I have some that I took out of some 286 equipment, and they still work.
I think there should still be the tests I did on those fans on the forum, without a sound level meter, by ear, with modelso and everything.

The topic of fans that have the winding outside, and therefore, usually only need the grip axis in the center, is something that the Veterans of this great forum :sisi: had already seen back in 2002. But trying to remember what it was called, and seeing that San Google didn't bring up any old model, searching for it as ML, I pulled up the forum's search engine, and then a little voice in my head (not the usual one, this one wasn't dropping F-bombs) said: TMD. And without being entirely sure if it was that or not, the search engine has shown me several posts (some perhaps of the first ones I created in HL :llorar:) in which we talk about them, and even with links to a review that still exists Review: Y.S. Tech TMD fan And now the posts loaded with nostalgia Those TMDs that have been talked about so much... Heatsink with TMD fan Fan without central motor Experiences with TMD fans from YS-Tech Enjoy them Salu2!

What I see is a more or less normal fan, but one that uses maglev in the rotor support.

We already had fans without mechanical noise with fluid bearings, I don't know if they are durable, but one with maglev, in theory, if it is well made, would have no or almost no friction and would be very durable.

Now what is needed is for someone to disassemble it and examine it in depth, in all positions etc, until then we have photos.

Regards.

P.D.: The TMDs, yes, the ones in the motor in the frame, I also remembered them, do they still exist?

[Fassou]

Don't get me wrong, putting the central engine next to the levitation system is definitely a challenge, but what could be a development test, or intended for the industrial market for equipment that can't afford the fans to ever fail (if the long life thing is met), ends up as a product for sale to the public, for the domestic market with that exorbitant price, with all the modding aesthetics with colors they put on it, I don't see that happening :nono:

Now, just to mess with you :troll: you'll see it blow up in sales

Best regards!

Man just came out and on top of that with "unheard novelty", they will have to lower the price a bit and by then the double pack will no longer be so exorbitant in price.
For my part I have yet to see how well the levitation works in different positions forcing both suction and pressure, depending on how it behaves in those directions it will be more or less expensive in my opinion.
The sleeve bearings wear out and you end up with rotor oscillation, vibration noise and loss of performance.
The rolling element bearings when they wear out produce more noise than all the others, even though they still keep the rotor centered.
The fluid dynamic bearings make no noise, supposedly they have no friction, no oscillation or noise over the years, but it seems to me that they don't work well in all positions and I don't know about reliability, I have a couple here that in vertical position I think they have been since the invention of the fluxus bearing.
It's probably not worth anything for the person who changes their entire PC every few years, but there are cases where it is, and if it were well made and detachable (cleanable) then it would also appeal to enthusiasts even if the tower is going to be gone in a few years.

I won't buy any of this until I see proof in time, no matter how much the theory says they are better. Same as I said above:
past and sunon from 20 years ago are still the same, the silentX lasted 3 months.

[Fassou]

I also had one of those SilenX fans die on me (they were 120mm gold ones and very wide), which scared me a lot, because it got stuck when I was using the computer, and the noise was terrifying :facepalm:

Cheers!

The theory you say is speculation, here we don't know anything yet.
Send us a set for analysis jjjj

It should be noted that, as a commercial product, it must have a balance between sophistication, innovation, and cost.
Could a fan be built without an axle, with no more friction than aerodynamic? Yes, but outside the industrial realm it wouldn't be profitable.

Out of curiosity I did a little research, it seems that there is a company called Sunon that has been marketing the same products for some time.

The TMD… damn what times. :fumeta:
